Electric Telehandler Central Battery Mounting for Weight Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric telehandlers face challenges in achieving a good weight balance, particularly when batteries need to be removed, changed, or their number increased or reduced, which affects the stability and compliance with regulations.
Innovation Solution
The telehandler design positions the electric batteries centrally between the front and rear sections of the supporting frame, ensuring better weight balance and minimizing the impact on lateral and front-rear balancing, even when battery size changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If electric batteries are positioned in the central section of the supporting frame, then weight balance is improved and stability is enhanced, but the complexity of battery installation and maintenance increases
Solution Approach 1:
The battery system is divided into modular units that can be independently installed and removed. Each battery module has standardized mounting interfaces that simplify installation while maintaining central positioning for optimal weight balance.
Solution Approach 2:
Batteries are designed to be extractable from the central section without requiring disassembly of the supporting frame or other critical components. This allows maintenance and replacement while preserving the stable central configuration.
2Power
If the number of electric batteries is increased to enhance power output, then the power and duration of action are improved, but the weight balance and lateral stability deteriorate
Solution Approach 1:
When multiple batteries are installed, they are arranged in an asymmetric configuration within the central section that compensates for weight distribution. This allows increased power output while maintaining lateral stability through careful positioning of battery masses.
Solution Approach 2:
The positioning parameters of batteries are adjusted based on the number and capacity of battery units installed. By changing the longitudinal and lateral positions of batteries, the system optimizes weight balance regardless of the total power output capacity.
3Ease of manufacture
If electric batteries are positioned away from the central section to simplify installation, then the ease of manufacture is improved, but the weight balance and compliance with stability regulations worsen
Solution Approach 1:
The central section of the supporting frame is designed with universal mounting structures that serve both stability functions (maintaining weight balance) and manufacturing functions (simplifying installation). This multi-functional design ensures regulatory compliance while ease of assembly.
4Duration of action of moving object
If the size of electric batteries is changed to adjust capacity, then the duration of action is improved, but the front-rear weight balance is adversely affected
Solution Approach 1:
The battery mounting system incorporates adjustable positioning mechanisms that allow the longitudinal position of batteries to be dynamically adjusted. When battery size or capacity changes, their position along the longitudinal axis can be modified to maintain optimal front-rear weight balance.
